N3-(sec-Butyl)-1-isopropyl-1H-pyrazole-3,4-diamine dihydrochloride (CAS 1431962-27-4), molecular formula C10H20N4HCl and molecular weight 232.76 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrile group, chlorine substitution, N3-(sec-Butyl)-1-isopropyl-1H-pyrazole-3,4-diamine dihydrochloride is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 232.76 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
CATO manufactures N3-(sec-Butyl)-1-isopropyl-1H-pyrazole-3,4-diamine dihydrochloride under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
